1 Claim.

This invention relates to containers, particularly shipping cartons of the type shown in Beaman Patent No, 2,214,220 dated September 10,

1940. The present invention has for its principal object to preserve the advantages of such cartons and at the same time increase the strength, rigidity and load carrying capacity thereof and provide an opening through the top end closure or cover of the carton and a removable plug cap for said opening that will give ready access to said carton. The invention consists in providing the carton with metal top and/or bottom end closures that are interlocked with and retained by the interlocking joint connections between the liberboard end closures and tubular'body of the carton; it also consists in providing an access opening through the top iiberboard and metal end closures to give access to the carton; it also consists in providing a removable plug cap for said opening; it also consists in providing the fiberboard top end closure with a iiberboard ring for reinforcing and stiffening said cover around the access opening therein; and it also consists in the partsv and combinations and arrangements of parts hereinafter described and claimed.

In the accompanying drawing,` which forms part of this specification and wherein like symbols refer to like parts wherever they occur,

Our invention is shown embodied in a carton of the type shown in Beaman Patent No. 2,214,220. Said carton includes a tubular body A and top and bottom end closures B and C, respectively. all made of corrugated board, liberboard, or other bendable sheet material. The tubular body A is divided into panels l by means of creasesor scores 2 extending longitudinally thereof and is made from afflat blank whose ends are overlapped and permanently secured together by staples 3 orotherwise.

Each panel I oi the tubular body A, has at each end a projecting ilap 4, a score line 5 facilitating folding of each ap into proximity with the outside face of the lpanel to which it is attached. The end closures B and C are of polygonal shape to iit the ends of the body member A and each side is provided with a projecting flap 6, score lines 1 being provided for facilitating bending oi said flaps, said flaps having continuations that are marked off by means of wide scores or creases 8 and constitute locking flaps 6a.

Each of the end closures B and C is placed opposite one end` of the tubular body TA, im flaps 6 are bent over the folded body panel aps 4 and the locking flaps 6a are rebent or tucked beneath said folded body panel flaps so as to lie between the latter and the body panels l. lThe flaps 6 of each of the end closures A and Bare provided with notches 9 in their adjacent edges to consti- ,tude locating recesses for a securing band or wire peripheral edge flanges I2 that fit over thefolded n panel aps 4 of said body, so that said iianges are interposed between said folded body panel naps and the folded iiaps 6 of said corrugated board end closure and are thus held against lateral movement relative to the latter and to said body.

As shown in the drawing, the corrugated board and metal end closures at the top of the carton have registering central circular holes I3 and I4, respectively,therethrough, forming an opening I5 through which access may be had to the contents of the carton, metal end closure B having a depending ange I6 delining the hole therein. Theopening l5 is closed by means'of a removable plug cap comprising a cup-shaped mtalldisk I'I adapted to iit said opening and frictionally engage the edge thereof and having. an outstanding rim iiange I8 that seats on the corrugated end closure B around said opening and serves to limit inward movement of said cap and to minimize leakage. f y

As shown in Fig. 8, the corrugated board top end closure B may be stifiened and strengthened around the hole I3 therein by means of an annular member I9 of corrugated board. fiberboard, or the like which is stapled or otherwise permanently secured, as at 20, to the underside of said end closure around said hole so as to form therewith the plug cap receiving opening l and thus prevent mutilation or tearing of said top end closure around the edges of said opening by repeated insertion and removal of the plug cap Il and the withdrawal of the contents through said opening.

The above described construction greatly increases the strength and rigidity of the carton at the top and/or bottom thereof; it also provides an opening in the top of the carton to facilitate access to the contents thereof without disturbing the interlocking flap connections between the berboard top end closure and the fberboard body or the clamping band which holds said end closure in place; it also provides a leakproof friction type closure member for said opening; and it also gives increased strength and rigidity to the bottom of the carton, whereby the carton is adapted to support a heavy load without bulging at the bottom and thus making it dicult to stack the cartons.

Obviously, numerous changes may be made without departing from the invention and we do not wish to be limited to the precise construction shown and described.

What we claim is: In a heavy duty shipping carton having a tu- 5 bular body and a closure for one end thereof, said body and end closure being made of iiberboard or like material, said end of said body having a series of naps that are folded alongside the outer face of said body and said end closure having a 10 series of marginal flaps that are folded over said body flaps and are thence rebent so as to lie therebeneath, the combination of a stiff metal interior end closure extending between said end of said berboard body and said berboard end ciosure next to the inner face of the latter and having a series of preformed marginal flanges disposed between the series of cooperating aps of said berboard body and end closure, said berboard and metal end closures having an opening extending therethrough, and said metal end closure having an inwardly extending flange surrounding lsaid opening, and a metal plug having a friction fit in said opening and an outstanding outer end flange seatingvagainst the outer face of said berboard end closure around said opening.
